Phyloecology of sea ice bacteria and archaea
This chapter takes a phylogenetic ecological approach to the introduction to sea ice microbes by weaving together our current knowledge of the diversity, distribution, and functions of individual tax....

Excited to share our new study exploring chemoautotrophy in subzero Arctic brines. We identified cold-adapted Rubisco enzymes in Thiomicrorhabdus species, suggesting unique adaptations for carbon fixation in extreme conditions. Read more: journals.asm.org/doi/10.1128/... #Microbiology #Astrobiology
Chemoautotrophy in subzero environments and the potential for cold-adapted Rubisco | Applied and Environmental Microbiology
Autotrophy, or the fixation of inorganic carbon to biomass, is a key factor in life’s ability to thrive on Earth. Research on autotrophy has focused on plants and algae, but many bacteria are also aut...

Hi 🧊bsky
I'll be chairing the GRS on Polar Marine Science in Italy this March!
We still have 10 seats available & 5 days left to apply!
Join our ECR community to share your research and discuss the role of sea ice in ecosystem dynamics!
